This role owns endtoend technical delivery-from data ingestion and modeling to AIdriven analytics-while ensuring strict data security, governance, and compliance suitable for highly regulated FinTech environments. Public AI services are

not permitted; all AI/ML workloads must run onprem or in private infrastructure.

What You'll Do

Data Platform & Snowflake Engineering

• Design and implement secure data pipelines to migrate and unify data from PostgreSQL, DynamoDB, and other source databases into Snowflake.
• Build and optimize ELT/ETL workflows, data models, and schemas in Snowflake for analytics and AI use cases.
• Own Snowflake performance tuning, cost optimization, clustering, and secure data sharing patterns.
• Ensure high data quality, lineage, and reconciliation between source systems and Snowflake.

Analytics & Reporting

• Build analytics datasets and semantic layers to support enterprise reporting, dashboards, and adhoc analysis.
• Enable selfservice analytics for business and operations teams using governed datasets.
• Collaborate with product and business stakeholders to define KPIs, metrics, and reporting logic.

Machine Learning & LLM Enablement (OnPrem)

• Design and deploy onprem ML and LLM solutions for reporting automation, anomaly detection, forecasting, and operational insights.
• Implement private / selfhosted LLM architectures (e.g., containerized or VMbased) with secure inference pipelines.
• Develop ML pipelines for feature engineering, training, validation, and inference using enterpriseapproved toolchains.
• Integrate AI outputs into applications, workflows, and reporting solutions.

Operational Efficiency via AI

• Implement AIdriven automations for operational efficiencies such as:
  • Automated report generation and narrative insights
  • Data anomaly detection and monitoring
  • Intelligent alerting and triage
  • Workflow optimization and decision support
• Measure and continuously improve AI model accuracy, performance, and business impact.

Application & API Integration

• Expose secure APIs and services for data access, analytics, and AI inference.
• Integrate analytics and AI capabilities with existing Java / Spring Bootbased services and applications.
• Follow secure API practices, including authentication, authorization, and tokenbased access.

Security, Compliance & Governance

• Enforce data security, encryption, access controls, and governance across PostgreSQL, Snowflake, and AI platforms.
• Ensure sensitive FinTech data never leaves approved infrastructure or flows into public AI models.
• Work closely with security teams to support audits, compliance, and risk remediation.
• Apply secure coding practices and address findings from SCA and security scanning tools.
